Energy-Efficient Cloud Computing
Energy efficiency is increasingly important for future ICT
Rapid growth of the demand for computational power has led to the creation of large-scale data centers
Energy savings are achieved by continuous consolidation of VMs

Introduction
Elastic characteristic of Clouds
In 2006 the cost of energy consumption by IT infrastructures in US was estimated as 4.5 billion dollars and it is likely to double by 2011
Virtualization technology allows : create several Virtual Machines on a physical server
improved fault and performance isolation
using live or off-line migration

Vision and Potential of Cloud Computing
Computer networks grow up and
become sophisticated!
Computing utilities based on a
service provisioning model
Users can access applications as services
from anywhere in the world on demand
Our Contributions to minimize the energy consumption

DVS-based Cluster Scheduling EDF-based scheduling
o The scheduler always executes the earliest-deadline task in the queue.
Proportional share-based scheduling
o Multiple tasks share the processor performance in proportion to each task’s weight.

Goal of this framework is to curb the energy consumption of Clouds without sacrificing the quality of service
GOC uses prediction algorithms to avoid frequent on/off cycles
The GOC framework relies on energy sensors (wattcmeters)

The VM reallocation problem can be divided in two: selection of VMs to migrate
determining new placement of these VMs on physical hosts

Concluding
As Clouds are more and more broadly used
New technologies have emerged for increasing their capacity to provide on-demand XaaS resources in a pay-as-you-use fashion
Propose an original software framework, the Green Open Cloud (GOC) which aims at controlling and optimizing the energy consumed by the overall Cloud infrastructure
This work advances Cloud computing field in two ways
